8 Claims.

This invention relates to bundles of lathers hairpins and a method ofproducing the same. The nature, objects and advantages will best beunderstood from the following remarks.

Lathers hairpins are employed for securing metallic lath to a supportingstructure, after which the plaster is applied to the lath. The hairpinis made of wire which can readily be bent by hand and will take a set.Annealed wire is ordinarily employed for the purpose. An end of thehairpin is hooked through an opening in the lath and bent aroundasupporting piece or structure, after which; the two ends may be twistedor otherwise secured together.

Ordinarily the lathers are supplied with a coil of wire for theirhairpins. The wire coil is merely cut up in pieces or in halves usuallyon the job. This cutting, obviously, is difiicult and troublesome forvarious reasons. For example, because of the character of the wire it isreadily deformed, the wires become tangled, are difficult to separate,and sometimes cause injury to the lathers hands. The entangling involvesa loss of time which is very objectionable because metal lath should becapable of being applied substantially as rapidly as wooden lath, ii notfaster. In addition, the common practice results in permitting the wiresto become coated with all kinds of dirt and the like such, for example,as bits 39 of plaster, all of which makes the wires difllcult to use aswell as unsatisfactory for other reasons which are well known in theart.

It is the primary object of the invention to overcome the foregoingdifliculties and to make the 5 hairpins readily available for thelathers at all times. Other objects and advantages will occur to thoseskilled in the art.

To this end I prepare the hairpins in advance, as will appear more fullyhereinafter in the I01- lowing description of the product as well as themethod of this invention, reference being had to the accompanyingdrawings in which,

Fig. 1 is a somewhat diagrammatic side elevation of apparatus suitablefor carrying out the 5 method;

Fig. 2 is a top view of the apparatus; Figs. 3 and 4 are viewsillustrating certain details of the apparatus;

Fig. 8 is a view similar to Fig. '7 of a modifie form of bundle wrapperor covering.

With reference first to Figs. 1 to 4 inclusive, in which I haveillustrated a suitable apparatus for carrying out the method of thepresent invention,

it will be seen that the lathers hairpins may be and are, preferably,made by continuously feeding wire from a source of supply such, forexample, as the reels 9. Any suitable type or number of reels may beemployed and the wire or wires indicated by the reference characters 10and 11, a total of four wires being shown in the present embodiment, maybe fed over suitable guide rollers 12 mounted on any convenientsupporting mechanism, as indicated at 13. The wires are next conductedthru any of the standard or well known wire straightening devices suchfor example, as those indicated at 14.

The coiling or winding mechanism illustrated includes a member 15 whichis mounted to revolve with and to be driven by a shaft 16, the latterbeing actuated by connection with any suitable driving motor ormechanism. The element 15 carries, preferably, a pair of arms or members17 and 18 each of which is recessed at a plurality of points, asindicated at 19 in Figure 4. With the members 17 and 18, mounted on therotating element 15 with the recesses 19 opening outwardly (see Fig. 2)the wires 10 and 11 are fed into and wound on the recessed portions ofthe members 17 and 18. The feed of the wires from the straighteningmechanism 14 to the winding mechanism is preferably accomplished bymeans of guide members 20 which may be stationarily mounted or providedwith some suitable manually operable devicefor causing a transversemovement thereof with respect to the elements 1'1 and18.v 1

At this point it should be noted that in the apparatus illustrated, Ihave provided for the winding of two coils of hairpin wire, but it is tobe understood that the members 17 and 18 may be configured otherwisethan as indicated in order to accommodate more than two coils. It shouldalso be observed that in the present embodiment of the invention, eachcoil is wound of or from a pair of wires which are fed to the windingmechanism simultaneously, that is, I have arranged for the winding oftwo wires 10 (see Fig. 2) on the outer set of recesses 19 of the members17 and 18 and, in like manner, have provided for the winding of twowires 11 in the other pair of recesses of the winding members. I may, ofcourse, wind each coil from a single wire or on the other. hand I maywind more than two wires into each of the coils produced. It ispreferable, however, to use more than one wire for each coil in view ofthe fact that the speed of production is greatly increased.

In order to facilitate removal of the coils from the winding mechanism,at least one of the members 1'7 or 18 is secured to the supporting androtating element 15 in such manner as to permit a radially inwardmovement thereof and thus provide for disengagement and removal of thecoils from the winding members. By reference to Figures 3 and 4, it willbe seen that the mechanism which I prefer to employ for this purposeincludes a slot-like aperture in the element 15, as indicated by thereference character 21, the same being adapted to receive the bolt 22 ofone of the winding'members, in this instance the member designated bythe reference character 18. In addition the base portion 23 of themember 18 is adapted to be received in a recess 24 in the element 15,the recess being of sufficient length to permit relative movementbetween the members 18 and 15 radially with respect to the shaft 16. Aswill be seen from inspection of Figure 2, a securing nut 25 associatedwith the bolt 22 serves rigidly to secure the winding arm or member 18to the rotating element 15. When it is desired to remove suitably woundcoils from the winding mechanism, therefore, it is necessary only toloosen the nut 25 and displace or move the member 18 radially inwardlytoward the shaft 16 after which sufficient clearance is provided tomrmit removal of the coils, for example, the coils indicated by thereference characters 26 and 27 in Figure 2.

The winding arm or member 17 is indicated in Figure 2 as being securedto the rotating element 15 by means of a bolt 28 and a nut 29. In theembodiment illustrated, the member 17 is not disclosed as being movableor adjustable with respect to the carrying element although, it is to beunderstood, such adjustment or adjustability could be provided in themanner indicated with respect to the arm 18.

After the coils are suitably wound and are severed from the source ofwire supply, they may be removed from the apparatus in the manner justdescribed and, preferably, thereafter cut or severed in order to producebundles of orderly arranged hairpin-like wires such as that illustratedin Figure 5 by the reference character 30. The production of the bundlesor groups of hairpin-like wires is preferably accomplished by cuttingthe turns of the coils, which are substantially elliptical inconfiguration, on their minor axes. Stated in another way, the turns ofthe coils are cut thru at points intermediate the relatively sharplybent portions of the coils (that is, the portions which engage thewinding arm Hand 18).

In addition to the foregoing the present invention has in view thepackaging of the individual groups 30 of hairpin-like wires in order tofacilitate handling, shipping and use of the hairpins. As a result ofthe novel packaging or wrapping the orderly arrangement of the wires ismaintained throughout the handling, shipping and use even whensubstantially all of the wires of any particular bundle have beenseparated or removed therefrom and used on the job.

The completion of each group 30 into a pack aged bundle includes theapplication of suitable tie means preferably in the form of tie wires.In the preferred embodiment tie wires 31 are applied to the legs of thegroup 30 at points intermediate the ends thereof, for example asindicated in Figure 5. In addition a wire 32 is applied in order to tiethe two legs together at a point near the extremities thereof.

After the application of the tie wires 31 and 32, each individual groupis preferably enclosed or covered in a-wrapping, such as a piece ofpaper which may/or may not be waterproof as desired, and it should benoted that I contemplate applying th' covering either by suitablyrolling the rasasos group, preferably, diagonally in a piece of paper asindicated in Figure 6 or by slipping the group, base end first, into acompleted bag as shown in Figure 8 and subsequently closing the mouth ofthe bag as by means of staples 35. After the application of the paper 33or the bag 34, additional tie means 36 are preferably applied in orderto secure all the elements of the packaged bundle together.

Furthermore, after the suitable packaging of the bundles, either by theuse of plain pieces of paper or by the use of suitable bags, has beencompleted, a supporting member or loop is applied to the bundlepreferably by piercing the wrapping or covering adjacent the baseportion thereof and by the insertion, thru the pierced portions of thecovering, of a wire 37. The ends of the, wire 37 may be suitably Joinedtogether as by knotting or twisting as indicated at .38 in Figure 6, 7and 8. The supporting member or loop 37 is useful in handling thebundles during shipping and the like and, in addition, afiords aconvenient means for supporting or hanging the packaged bundle on thejob while the hairpins are being used.

The preferred manner of use of the bundles will be apparent frominspection of Figures 7 and 8, in the first of which a bundle isillustrated as being hung from a supporting member such as a nail 39,the supporting loop 37 being shown in engagement with such nail. Aftersuitable hanging of a bundlein this manner, the upper portion of thecovering 33 or 34 thereof is torn away as indicated, respectively, inFigures 7 and 8, in order to expose the base portion of the packagedbundle 30. With the base of the hair pins so exposed, a workman mayWithdraw the hairpins piecemeal, i. e., one or several of the hairpinsmay be withdrawn from the bundle and suitably employed in the attachmentof metallic lath to wall structures, it being noted that while this useis not the only one to which the hairpins are adapted, still this.particular use brings out the advantages and importance of variousfeatures of the bundle. The manner in which the hairpins may be removedfrom the bundle is clearly indicated in Figure 7 in which a hairpin 40is illustrated as being partially withdrawn from a bundle. At this pointit should also be noted that the manner in which the covering orwrapping of the bundle is secured thereto permits the base portionthereof to betorn off in order to expose the hairpins and, at the sametime, prevents complete uncovering of the wires during their use.

In summing up, it should be observed that the wrapped bundle produced isof such form as completely to eliminate injury to the wires in handlingprior to use. In addition, the packaging employed keeps the hairpinsclean both before and during their use. In view of the form thereof,when a bundle is opened with ordinary care, the wires will not betangled, and hairpins can be removed from the bundle very readily.Furthermore, the hanging of the bundle from a nail, hook, or the likeprevents the hairpins from becoming interwoven or entangled. In thisconnection, it will readily be appreciated that in accordance withthe'usual practice, when the lather cuts his hairpins from a coil ofwire of the usual configuration, the workman is not only substantiallyhampered inmaking application of lathing by reason of the additionaltime involved, but, in addition, the groups of hairpins which he may cutfrom his coil of wire must be laid aside and almost always become dirtyas well as intertwined or interlaced in such manner as to causeadditional loss of 150 time, as well as wastage of wires. The result isthat frequently a lather must discard large groups of mixed up or dirtywires.

The present invention completely overcomes the above noted difficultiesand affords the maximum convenience and efliciency, as well as economyin the application of lathing.
